TO ALL WHOM IT MAY CONCERN:

Be it known that I, G. M. PETERS, of Granville, county of Licking, andState of Ohio, have invented a new and usefulImprovement in Rakes forHarvesters; and I do hereby declare that the following is a full, clear,and exact description of the construction and operation of the same,reference being had to the annexed drawings, making a part of thisspecification, in which- Figure 1 is a plan or top view of a harvestingmachine embracing my improvements,

Fignre 2 is a bottom view thereof.

FigureB is a sectional view of the same, taken in line :5 w, fig. 2.

Figure 4; is a detached view, showing the guide-rod, weighted latches,&c., for governing the movementsof the rake-lever, and

Figures 5 and 6 are also detached views, hereinafter explained,

Similar letters of-reference indicate corresponding parts in all thefigures.

My invention consists in the employment of areciprocating andturning-rake operating from beneath, through a slotted platform, and soarranged as to sweep the grain from the platform of the machine in apath which is parallel with the finger-bar in a portion of its length,and then to turn in-thc arc of a circle and dis charge the grain behindthe inner end of the platform, out of the way of the team and machine onits next .round, as hereinafter explained; and it further consists in anovel arrangement of means for operating the rake in the manner aboveegplained. I I

To enable others to understand and use my inrcntion, I will describe thesame with reference to the draw ings, in which- A is the main frame'ofthe machine. 13 the main carrying and driving-wheel, provided with theusual spurgear, and from which motion is imparted to the cutter througha pinion on the end of counter-shaft a, driving 'bevel gears I; c,crank-shaft d, and pitman e, as shown in the drawings, or in any desiredmanner. 0 is the fingerbar, bolted or otherwise firmly secured to frameA in line or nearly in line with the front transverse bar of frame, asshown at C, and to which the guard-fingers c are connected in the usualmanner. D is abar attached to the rear of the main-frame, and arrangedin a line parallel or nearly so to the fingerhar, and connected at itsouter end to the outer orframe end of the fingerbar by the longitudinal,bar or frame-piece E, the bars 0, D and E forming, in connectionwithinner longitudinal bar of frame A, the frame for the support of thegrain platform and raking apparatus, hereinafter described. F is theplatform, which maybe made of sheet metal or other suitable material,slotted in a portion of its length, in lines parallel with thefinger-bar, as shown in the drawing, at points therein'niarkedfg, fromwhich latter point, g, the slots are formed in the are of a circle, ofwhich the point or pivot m, hereinafterreferred to, is the centre, andterminate at the frame bar D, at the inner rear eornerof'the platform,as shown at in. G G are curved strips or plates of metal, of a formcorresponding to the form or curvature'of the slots in the platform, andsecured to the platform by means of shouldered bolts or rivets, at asuitable distance beneath the same to accommodate a reciprocatingcarriage, 11, moving on frictionroller 2', between the said guides andthe platform, as shown in fig. 8. The carriage is further provided withfriction-rollers'z" attached to its under snrfac'e and working over theopposing faces of the guides G G, as shown in figs. 2 and 3. I is therake-head, provided with teeth I, which, when the rake is dischargingthe grain, pass up through the slots in the platform, (see fig. Saidrake-head is supported in lugs j, underneath the carriage H, in suchmanner as to be free to turn thereon, (see figs. 3 and 6.) J is acrank-arm or lever, secured to the rake-head in suchmanner as to causethe rakehead to turn with it. Said arm is provided with an arm or stop,,7", which, when the rake-teeth are raised to discharge the grain,strikes against the carriage H, and preventssaid teeth from passingbeyond a vertical position. The opposite end of arm or lever Jisprovided with an'eye to receive a pivot passing through correspondingeyes in one leg or arm of loop K, as shown in fig.

6. -L is a slotted-lever, which passes through the loop K, and isconnected thereto by means of pin it, provided tvith friction-roller 7a,which works back and forth in the curved slot Z, in lever L, ashereinafter explained.

Lever L is constructed in form'sh'own in figs. 2 and 3, and is pivotedat the rear and near the outer corner of the platform, on the elongatedpivot on fulcrum pin m, and is provided with a spur, it, having afriction roller,

.Which works overand under a curved horizontal guide, M, on the oppositeends of which are weighted or w some spring latches or gates, at m forpermitting and controlling the vertical movements of levers L. N is apendant connected to theunder side of the platform or to rear bar D, andprovided with an angular arm or inclined way N, over which the roller77/ passes, and by which the rake-lever L is raised in passing the latchm. '0 is a curved arm or way attached to the platform at the oppositeend of guide-way ortrack M, underneath which the roller' passes at'ornear the end of its return movement, and by which a downward movement isgiven to the rakelever in passing gate in, for a purpose hereinafterexplained. The lever L extends in rear of its fulcrum pin m, and isconnected, at its rear end, by link or pitman 0, to one end ofreciprocating rod or bar 0, sliding in hearings or lugs, o 0. Said rodis connected by link or pitman o to crank-arm 0", on one end of shaft12, which is mounted in bearings on the main frame, and which isprovided at its opposite end with the bevel-wheel g, which meshes withthe bevel-wheel g on the end of the main drive-wheel axle, as shown infigs. 1 and 2.- Q is a forked-lever, arranged within convenient reach ofthe driver, on seat R, for the purpose of enabling him to slide thebevel-gear g on its shaft 27, into or out of gear with bevel-gear g. Qis a similar lever, alsolocated within convenient reach of the driver,for sliding the pinion on the coui'iter-shaft, and thereby throwing .itinto and out of gear with its driving spur-wheel for stopping orstarting the cutters. B is the grain-wheel, carrying the outer or grainend of the platform, arranged in line with the driving-wheel, and.insuch relation to the platform as to support the outer end at the sameheight from the ground as the inner end. S is a curvedlever, pivoted tothe tongue 1 at a", and connected at its forward end by a chain or link,.9, to the finger-bar or frame A. Said lever extends back into aposition convenient to be operated by the driver on seat R. Tis thereel, mounted in standards t t, as shown in fig. 1, and provided, at theinner end vof its shaft, with pulley U, to which motion is imparted by abcltfroni pulley U on the inner end of the main axle, or in any usual orconvenient manner. V is an inclined slotted grain-guard-or deflector atthe grain end of the machine, by which the grain cut by the-outer end ofthe cutting apparatus is thrown inward toward the centre of theplatform,'and

which is of suiiicient width to enable the teeth to be raised to thevertical position before coming in contact with the grain on theplatform. Wv is a foot-board, whieh'may be either attached to the seatstandard or to the main frame in any convenient manner.

The operation of the cutting apparatus, reel, shifting-levers, (be, willbe understood without further description.

The operation of the rake is as follows, viz: The machine being drawnforward in the usual manner, motion is imparted from bevel-wheel q tobevel-wheel (1 on shaft 12, and crank 0 and through pitman oreciprocating rod 0, and pitman-o, to the rake-lever L. The parts beingin position shown in fig. 1, in which the rake has just completed thedischarge of a gavel, the roller 91,, on spur n of the rake-lever, iscaused by the rotation of the crank o to move outward over thehorizontal track or way M, in position and direction shown by dottedlines and arrow 1, fig. 4, until it reaches the curved rod or guide 0,underneath which it passes, forcing the weighted latch in down with it,when, having passed the latch, the latter resumes its former positionshown in dotted lines, fig. 4, when the rake-arm, having reached the endof its ineffective stroke, commences its return movement, and the rollern being forced underneath the way M, by the position of the latch,causes a downward reciprocation of the lever, carrying the end of arm orlever J, attached thereto, down with it, thereby turning the rake-headto which lever J is attached, and causing the teeth to assume a verticalposition, as shown in figs. 3 and 5, for sweeping or discharging thegrain oil' 'the platform, the roller 11 passing back underneath thetrack M, as shown by dotted lines and arrow 2, fig. 4. Therake-leverturning upon a fixed point, the vibration of the rake end isin the arc ofa circle, of which the fulcrum pinm-is the centre, but, thepath or way in which the rake-carriage moves, being for a portion ofits' length in a path parallel with the finger-bar, the pin connectingsaid carriage to'the rake-lever is permitted to move-freely back andforth in the slot in the outer curved end of the lever, to compensatefor the varying distance of the rake-carriage from the fulcrum m. Whenthe rake has nearly reached the end of its delivery stroke the rollern'is caused to rise over the inclined track N on pendant N, carrying theweighted latch m with it until it passes saidlatch, when the rake,having completed its delivery stroke, the rake-arm is lifted by roll'drn, passing back over the latch, carrying that end of lever J with it,thereby turning the teeth downward into a horizontal position out of theway of the grain lying on the platform. Yis a grain-board at the innerend of the cutting appartus and platform, conforming in shape nearly tothe curved path of the rake during the latter part of its movement indischarging the grain, andwhich serves to prevent the scattering of thegrain during the operation of discharging the same. v

I have now described one good practical-way in which my invention may becarried out in practice, but it will be obvious that changes may bemade, as in the construction of the frame, the employment of twodrivingwheels instead of the one described, and of the specific devicesthrough which motion is communicated to the rake, without departing frommy invention. 7

What I claim as my invention, is-- 1. A reciprocating and turningrake,operated from beneath, through a slotted platform, and arranged to movein a path parallel with the finger-bar during a part of its deliverystroke, and then to turn and sweep the grain from the platform in thearc of a circle, the centre of which is at or ncarthe rear outer cornerof said platform, substantially as described.

2. A grain-platform, slotted as described, in combination with areciprocating and turning-rake operating from underneath, and deliveringthe grain inrear of the inner or main frame-end of said platform,substantially as described. p

3. The reciprocating turning rake, in combination with'ith-e lever .Tand slotted sliding-lever L, operated as described.

4. The reciprocating rod 0, Working underneaththe rear edge of theplatform in guides o 0, iii combination with connecting rods or links oo, and slotted lever L, as described.

5. The rake-lever L provided with the spur and frictionroller.asdescribed, whereby a, vertical reciprocation is imparted to saidrake-lever through the medium of ways or tracks M N O, and latches m mor their equivalents for the purpose specified. v i i In testimonywhereof I have hereunto set my hand this twenty-third day of April,1867.
